Hi @Sheng, Wenhui,
I'm thinking of hiding the MP0/MP1 mode 1 reset under AMD_RESET_METHOD_MODE1. the callback function reset is per ASIC function, where nv_asic_reset and soc15_aisc_reset serve for NV series and pre-NV series respectively.
The new mode 1 reset will be used starting from sienna_cichlid. It should be quite strait forward for us to either initialize a flag like is_smu_support_mode1 during sw_init or even check the asic_type in nv_asic_mode1_reset to decide whether we use psp_gpu_reset or smu_gpu_reset.etc.
That's saying, we don't need to change the reset_method interface, where we decide whether we go to BACO/mode reset/pci config space reset.etc. We just differentiate the approach (i.e. psp or smu) in nv_asic_mode1_reset.
Thoughts?
Regards,
Hawking

Subject: [PATCH 2/4] drm/amdgpu: add psp mode1 reset mode
AMD_RESET_METHOD_MODE1 will be used by SMU
mode1 reset for sienna cichlid, so add
AMD_RESET_METHOD_PSP_MODE1 for psp mode1 reset.
